BRICK-.ANCHORlNG MEMBER.

Application filed October 3, 1924. Serialr N'o. 741,304.

My invention relates to anchoring members and especially to anchoring members for furnace walls. The invention may also be found applicable to other structures in which the advantages hereinafter pointed out would be useful.

The nature, objects, and advantages of my invention will be best understood from a description of the invention as applied to a hollow wall construction of a pulverized fuel burning furnace, for which, because of the expansion and contraction conditions, the invention is particularly adapted.

In the drawings, Fig. 1 is a face View of my anchor device, the supporting girder andrecessed brick being shown in dotted lines.

Fig. 2 is a plan view of Fig. 1 and Fig.' 3 is a fragmentary vertical section through a hollow furnace wall and supporting structure embodying my invention.

Referring to Fig. 3, I have here shown a hollow wall construe-tion such as used, for instance, in pulverized fuel furnaces comprising a refractory wall 7 relied on principally to withstand the intense heat within the furnace/,and an outer structure or shell 8 relied on as the main elementof structural strength for the wall. This outer wall is composed 'of horizontal girder members A, which may be supported by upright buckstaysL (not shown) and a thermo-insulative layer 9, betweenv the' horizontal girders A, supported and heldin lposition bythe gird- The innerwall is supported or positioned by the outer wall to which end holding tile B are provided in the inner wall. The holding tile not only serve as a means for dividing the space in the wall into horizontal compartments but also as a means for connecting the inner wall to the outer wall. The tile B are recessed as indicated in Figs. 1 and 2 so as to provide T shaped openings 10 between adjacent tile extending the full thickness of the tile. Each one of the T shaped openings or reentrant recesses 10 is adapted to receive an end of one of the anchorage membersC to be now described.

As best shown in Figs. 1 and 2 each anchor member C is `of vsubstantial T cross section with the head'of the T adapted tov interlock with the T openings or reentrant recess 10. The leg of the Thas means for engaging the support or girder A, such means in this instance being a couple of inturned' fingers 11 and 12 which interlock behind the corresponding girder iange. Horizontally the anchor C may be held xedi by engagement of the fingers 11 and l2 between portions of the thermo-insulative layer 9. The finger 11 extends well beyond the point of engagement with the girder A., thereby providing means for holdingA the anchor member firmly by the insulative layer 9 against longitudinal movement. The gap betweenI the points 13 and 14 of the fingers is greater-than the width of the flange 15 of the girder A. This permits of vertical movement of the member C so as to prevent any binding. A certain amount of swinging movement may also be imparted to this member by virtue ofthe space 16 between the'lower finger 12 and the fiange 15, the upper linger fitting the flange relatively snugly in comparison.

.Bosses 17 arev provided on the web or leg portion of the anchor member tov afford spot Contact with the girder.y c

The head 18 ofthe anchor member has its outside .surface 19 curved both vertically and horizontally, and its inner surface 20 curved vertically and tapering toward the leg of said member. In other words the head may lbe said to bulge at its central portion, at

which portion the brick contacts for rocking movement both vertically and horizontally.

Since the inner wall is next to the zone of combustion it obviously expands and contracts to a much greater extent than the outer shell. By virtue of the anchoragevr arrangement provided the, inner wall is free to expand and contract with reference to the outer wall and this without imposing any great stresses on the holding tile, for the reason that the holding tile can rock both horizontally and vertically with respect to the anchor, and the anchor itself can rock vertically on its supporting girder, as Well as shift vertically bodily. The advantage of this will be appreciated when it is understood that if the holding ,tile should break oit' the entire wall would collapse.

The inner wall shields the metal from the heat and in addition the current of air which flows through the compartments of the wall and passes into the furnacek through the rows of openings 21 also serves to protect the metal against the heat.
